Title: Servo circuit
Inventor: TANAKA HIROMICHI
IPC: G11B21/08
Filed: 1982-02-22
Abstract: PURPOSE:To attain random access smoothly, by providing a reference signal generating circuit of the same frequency with a synchronizing signal, and inputting the signal of said circuit to a phase detecting circuit as the synchronizing signal during the random access operation, and holding a servo circuit in a locked state. CONSTITUTION:When a switch 16 is at a side fD, the output signal fPD of the phase detecting circuit 10 is the phase difference output between the output signal fD of a synchronizing signal detecting circuit 5 and the output fX of a reference oscillating circuit 13. Once an instruction for random access is inputted, the output signal fD of the synchronizing signal detecting circuit 5 becomes unstable, so the switch 16 is changed over to a side fH synchronously with the instruction input and a switch 17 is turned off. Consequently, the output signal fH of an oscillating circuit 14 is inputted to the phase detecting circuit 10 and the synchronizing signal in a servo loop is supplied to hold a servo locking state, thereby causing a track jump for the random access.

Title: Supply element for fluid
Inventor: ODA HAJIME
IPC: B41J2/175
Filed: 1982-02-19
Abstract: PURPOSE:To relax the variation of pressure of a high-frequency component, also by  combining a liquid chamber and a liquid chamber through two plates forming a thin  layer and forming a dimple to the surface of an orifice plate on the side facing to a  liquid supply layer. CONSTITUTION:When a liquid passes through a head through the liquid supply layer  10 from orifices 8, 9, the variation of pressure of the high-frequency component is  absorbed by the dimples 17 formed to the surfaces of the orifice plates 6, 7 facing to  the liquid supply layer 10. The high-frequency component is removed when the fluid passes through a path in which sections with large sectional areas and sections with  small ones are constituted alternately. Since the liquid enters from the orifices 8, 9  and flows in the liquid supply layer 10 while being expanded in the radial direction of  the orifice plates 6, 7, the sectional area of the liquid supply layer 10 through which  the liquid passes expands with advance in the radial direction, and frictional resistance  is reduced inversely. That is, the variation of pressure of the high-frequency component of frequency extending over a wide range can be absorbed and relaxed because the velocity of flow and frictional resistance of the liquid passing through the liquid  supply layer 10 change in the radial direction in the layer 10 formed by the dimples 17.
